I am having the problem with my Nokia N900 keyboard backlight and Notification light. The backlights of the keyboard have stopped working completely and also the notifications light have stop working. I have gone thought the setting in the phone for the notification and found that the setting are been changed. The light dies not work for any of the indication for any function. The keyboard is the major issue I am facing, when I have to type something in dark night. Other than this issue I am pleased with my N900. So guys please help me to overcome the solution.
